Mapping the space of integrable equations (12:00 PM - 1:00 PM) -- Abstract: The KdV equation is historically the most important example of an integrable equation. It being integrable, this nonlinear equation exhibits exact soliton solutions which are stabilized by the existence of infinitely many commuting symmetries. Although originally used to model non-relativistic shallow water waves, the KdV equation has inspired calculation methods in more fundamental settings, and even shows up in some gauge and gravity theories. What makes the KdV equation so special? Does it fit into a bigger picture of integrable equations? Making use of the classical chiral algebra of the scalar 2d CFT, I will show how the KdV equation and its hierarchy is maybe the simplest example of an integrable hierarchy, and that there are many more, quite exotic, integrable equations which generalize the KdV equation. I will solve new necessary conditions on all possible integrable equations of the KdV type, finding a restricted parameter space, with the KdV equation a special point in this space. |
